For server applications, memory modules and other server components must withstand almost non-stop exposure to elements such as heat and electricity. The slightest defect can become a problem resulting in server crashes and data loss for multiple users.

As server memory capacities increase, so does the likelihood of memory errors that can corrupt data and cause servers to crash. This part is cataloged in the U.S. Government catalog under NSN 5962-01-554-4162, indicating validated use in U.S.
